Three black - almost spherical shapes hover and then take off at rapid speed in crowded city

I was driving along in the city; headed to an outdoor movie @ around 8:30 {keep in mind it is still light out as it was in July} - I was stopped at a red light and looked to my left as I had seen something in the corner of my eye. I thought at first that they were helicopters, as in Baltimore city helicopters fly uncomfortably low. I realize now that was just my natural reaction as a human, trying to relate something insane to something known. I looked harder as they started flying lackadaisically over one another. I grabbed my iPhone (for those of you who are familiar, when you click the button there is a swipe feature allowing the camera to open in about 20 seconds) and did so.

By the time my camera was up (about 30 seconds) they had flown high above me into the clouds, barely visible but I was able to snap a few photos for proof. HA!
